MYRON COSSEY, OF NEW YORK, N. Y., ASSIGNOR TO RELIANCE BALL BEARING DOORHANGER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

LATCH FOR DOOR-HANGERS.

To allwhom it may concern:

Be it known that I, MYRON GossEY, a citizen of the United States, and aresident of the borough of Brooklyn, city of New York, State of NewYork, have invented certain new and useful Improvements in Latches forDoor-Hangers, of which the following is a specification.

My invention relates to improvements in latches for door hangers and isespecially adapted to be used with the form of door han er, such asdescribed in my earlier patent 0. 632,224.

In the accompanying drawings, in which similar reference charactersdesignate corresponding parts, Figure 1 is a front elevation of aconstruction illustrating my invention as applied to an elevator door;Fig. 2 is a plan view; Fig. 3 an enlarged view in detail; and Fig. 4: aView similar to 3, but showing the parts in a different operativeposition.

Referring now to the drawings it will be seen that I provide a doorhanger comprising two outer bars C C and an intermediate bar B withantifriction devices between the bar B and each of the bars 0 and C. Thethree bars are arallel and the outer bars constitute one e ement and theintermediate bar another element and one of these elements is movablelengthwise with respect to the other. In the present case, I have shownthe bars C C fixed and the bar B movable between them. A door A isconnected to the bar B by strips a a.

Obviously, if preferred, the intermediate bar 13 might be rigidlysecured to the supporting structure and the bars C and C socured to themoving body or door. In either event, we have the necessary respectivemovement between the intermediate bar and the outer bars.

To the immovable or fixed element, in this case the bar 0, I rigidlysecure a lug or projection D which, as shown, has its under surfacearranged on an incline d. To the movable element, in the ease the bar B,I rigidly secure what I may call a latch socket E in which is supporteda movable latch F. As shown, this latch is vertically movable and hasits upper face inclined substantially to correspond with the incline don the lower face of the immovable lug D.

Obviously, when the door is in the posi- Specification of LettersPatent.

tion shown in Figs. 1 and 3 and the latch F in its extreme upwardposition, the bars B and C will be securely locked to prevent anyopening movementof the door.

Any suitable means for operating this latch may be employed. I haveshown it mounted on the top of a connecting rod G, suitably supportedand surrounded throughout a portion of its length by a spiral spring g,which is contained under pressure between two sleeves g g The lower endof the connecting rod G is shown as being pivotally connected at h tothe lower arm it of an operating lever H. As the lever II is pushed tothe right in the drawings, the rod G and also the latch F are drawndownward against and overcoming the tension of the spring 9, thusdrawing the latch F out of engagement with the stud D and permitting thedoor to open. If the door is open and moved to a closed position, theinclined upper face of the latch F is forced into contact with theinclined lower face of the stud D. This forces the latch F downwarduntil its extreme upper point passes the extreme lower point of the studD. Then the spring g immediately forces the latch upward, thus securelylocking the parts in a closed position.

As shown, the operating lever H is pivotally seeured to the door A andnear the back edge thereof. This location of the lever and latch andconnecting parts is a great advantage in many cmistructions in that itenables the operator to open the door without reaching across the same.

l1, designates a stop for preventing the possibility of the lever armbeing forced too far over. Any other suitable form of stop may beemployed to limit the movement.

IIaving described my invention I claim:

1.. A door hanger comprising three parallel bars, the two outer ones ofwhich constitute one element and the intermediate bar another element,one of said elements being movable with respect to the other, and meansfor connecting the movable element to a door, combined with a movablelatch on the movable element and door, and a stud on the other elementwith which said latch coacts to prevent movement of the movable element,and means for moving the latch.

2. A door hanger comprising three parallel bars, the two outer ones ofwhich constitute one element and the intermediate bar coacts to preventmovement of the movable another element, one of said elements beingelement, and means for operating the latch. movable With respect to theother, means or .3 connecting the movable element to a door, MYRONGOSSEY' combined With a movable latch mounted to Witnesses:

move with said movable element, and a stud M. H. SGI-IWEITZER,
